CardioMEMS-Guided Heart Failure Management in Cardio-Oncology Patients: A Tertiary Care Cancer Center Experience

Growing evidence suggested an association between aortic valve sclerosis (AVSc) and cardiovascular (CV) events. However, little is known about the association of AVSc with major markers of subclinical atherosclerosis. We performed a meta-analysis of literature studies to address this issue.Studies on the relationship between AVSc and common carotid artery intima-media thickness (IMT), prevalence of carotid plaques (CPs), flow-mediated dilation (FMD), aortic pulse wave velocity (PWV) and augmentation index (AIx) were systematically searched in electronic databases. Thirteen studies enrolling 1086 AVSc patients and 2124 controls were included.Compared to controls, AVSc patients showed higher IMT (MD: 0.32 mm; 95%CI: 0.07, 0.58; p = 0.014), and higher prevalence of CPs (OR: 4.06; 95%CI: 2.38, 6.93; p < 0.001). Moreover, lower FMD (MD: − 4.48%; 95%CI: − 7.23, − 1.74; p = 0.001) and higher PWV (MD: 0.96%; 95%CI: 0.11, 1.81; p = 0.027) were found in AVSc subjects than in controls, with no differences in AIx (MD: 0.76%; 95%CI: − 0.97, 2.49; p = 0.389). In meta-regression analyses, body mass index and triglyceride levels have an impact on the difference in IMT between cases and controls, while male gender and smoking habit were associated with the difference in the prevalence of CPs between the two groups.AVSc is significantly associated with altered markers of subclinical atherosclerosis, thus supporting the concept that AVSc and atherosclerosis share common etiopathological mechanism and/or risk factors.
